SIGNIFICAND(3) Linux Programmer's Manual SIGNIFICAND(3) NAME significand, significandf, significandl - get mantissa of floating- point number SYNOPSIS #include <math.h> double significand(double x); float significandf(float x); long double significandl(long double x); Link with -lm. Feature Test Macro Requirements for glibc (see feature_test_macros(7)): significand(), significandf(), significandl(): _SVID_SOURCE || _BSD_SOURCE DESCRIPTION The significand() function returns the mantissa of x scaled to the range [1,2). It is equivalent to scalb(x, (double) -ilogb(x)) This function exists mainly for use in certain standardized tests for IEEE 754 conformance. CONFORMING TO These functions are nonstandard; the double version is available on a number of other systems.
